When there is sound you should see movement on the screen bar. Set the sound input level so that the Peaks reach approximately 0 d. B on the RH side of the screen. If there is no movement on the sound level bar check connections and the input selection. If all is OK press the red “Rec” button again and it should start recording. You will see the timer counting and movement on the sound level bar. Also the recording light will turn on. Press “Stop” to finish the recording.

Recording sound To transfer the sound files to a computer use the USB socket and supplied cable. I have the recorder output set to the uncompressed WAV format for best quality. Use software to edit the sound file for length, any deletions and to “normalise” to final sound level. Convert to the MP 3 format using a 128 Mbit setting.
